CAR-HAUL.

To allwhom it may concern.:

Specification of Letters Patent.

Application led February 24, 1909.

va citizen of the United States, anda .resident of Cleveland, county VofCuyahoga, `and State of Ohio, have invented a newand useful Improvementin Car-Hauls, of which the folflowing is a specification, the principleof the `invention being herein explained and the best inode `in which Ihave contemplated apl plying that principle, so as to distinguish it'from other inventions.

The present invention relating as indicated to car-hauls, has moreparticular regard to the provision of means for retarding the speed ofcars when shunted on the main .track of the haul from the shiftingtrack,

whereby such cars may -be delivered without shock to the hooks ofthehaul chain.

The object .of the invention Ais the provision `of simple and eectivemeans for accoinplishing this result, which means shall;

furthermore be entirely automatic in their1 operation.

To the accomplishment of .this and Vrelated 2 ends, said invention thenconsists of theE Ameans hereinafter fully `described and par-.

ticularly pointed out in claims.

The annexed drawing and the following Vdescription set forth in detailcertain mech-l anisms embodying the invention, such dis-2 closedinea-iis constituting, however, but one@ of various mechanical forms inwhich the principle of the invention may -be used.

In said annexed drawing Figure 1 is a` diagrammatic side view of a carhaul illus-` tiating one inode of installing my improved constructionreferred to above; Fig. 2 is a side elevation on a considerably largerscale,

of a detail of the haul chain, showing thej parts thereof in oneoperative position; while Figs. 3 and 4 are similar Views of saiddetail, showing the parts in other operativey positions.

My improved car-haul construction, inf volves the use of a hump, orraised portion,

in the track, which hump is designed to be of suficient elevation, toovercome the iinpetus of the car that is shunted on to the said 2 track.This feature Aof a hump is not pre-y sented as being broadly new, thepresent invention being directed to the provision of means for properlyplacing cars with respect to the car haul chain; as such cars aredischarged oiito the main haul track for, as will be obvious, unless theelevation of the hump vquestion.

ythereover, `it will run up as far as its initial impetus will carry it,and then move backwardly, in which event it will be apt to encounter-the succeeding car with .prospect of damage and interruption ofoperation.

Referring first of all to Fig. l, showing as lhas been stated, but onetypical illustrai tion of -iny improvement, A 'represents the track of alowering, or down haul along which passes in the direction indicated bythe arrow, the down haul chain B. The latter is provided at suitableintervals with hooks or dogs b in the present instance to engage withthe forward axles of cars on said track to retard their movement, aswill be readily understood. The track or stai tion from which the carsare fed on to the main dowii haul, is not shown, but the portion of suchhaul immediately adjacent to such station, is inclined upwardly, as isshown, so as to form a hump a of the character 'hereinbefore referredto. From such hump the track A accordingly inclines downwardly in A'bothdirections. The portion of the down haul chain, B corresponding withinclined track-section A is depressed for the major portion of suchsections length so as to bring the dogs b below the level where they areeffective to engage the car,y and is not until approximately the summitof the hump is reached that the chain is elevated to the proper positionfor engaging cars. A car discharged onto the track, it will accordinglybe seen, is free to move along the same to such summit, before it willbe engaged by the hooks in Associated with each of these ldogs '2),whereby forward movement of the car, when the chain is properlypositioned, is prevented .other than in unison with the chain, isasecond oppositely disposed dog rising to substantially the same heightand provided with a pivoted member b2 that in the normal uprightposition in which its own weight maintains it, rises a sufficient llOdistance above the height just indicated, to engage a car axle evenalong that portion of the track, where the chain is depressed in themanner previously described. Such pivoted member moreover is free tomove in a forward direction e. toward the other dog of the particularpair in question) only, being located against movement in the oppositedirection. By reason of this construction of the pivotal dog portionZ22, it does not interfere with the forward movement of a car up ontothe hump but will prevent such cars return, so that it will be retainedat whatever point it may have reached in ascending the hump and becarried on over, by virtue of such engagement. As the summit is reached,both of the dogs, as has been stated, rise to full operative position,and the axle is now held, not merely against backward movement by theauxiliary dog b, but is safely positioned behind the forward dog b thatprevents it racing down the car haul proper. The successive relativepositions of the two dogs and the axle c, of a car C, will be clearlyunderstood by reference to Figs. 2, 3 and i, in the first of which theaxle is shown as passing over the rear or auxiliary dog, the pivotalmember b2 of the latter appearing in depressed position; the second viewrepresents such axle after passing over dog in question; and the thirdrepresents the axle safely pocketed between the two dogs and in contactwith former, which is the position occupied pending descent of the downhaul.

From the foregoing' description of the construction and operation of myimproved car haul, it will be obvious that its action is entirelyautomatic and positive. At the same time its simplicity, compared withthe auxiliary hauls and like contrvances that have heretofore beenemployed in this connection, will commend it. By way of conclusion itshould be remarked that the construction of dog shown, may by simplereversal in position be adapted equally well for the feeding of carsonto a haul arranged to convey such cars from a lower to a higher level.No modification of construction being required, it is not deemednecessary to illustrate the arrangement of apparatus for this purpose.Moreover, my improved construction of haul is not limited necessarily touse with a track having a hump or one, in other words, that inclinesoppositely in different portions; but one such portion may be disposedhorizontally, that is on the level without introducing any variation inthe principle of operation involved. This remark applies moreparticularly to the upper section A of the haul as illustrated. Noteshould finally be made that the word cable as herein employed isdesigned to connote not only a cable (2'. e. a rope) in the strictersense of the term but also generically either a chain or any equivalentextended hauling or pulling means.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my inventionl. In a car-haul, the combination with a track inclining downwardly inboth directions from an intermediate point; of a cable passing alongsaid track and provided with a plurality of spaced pairs of oppositelydisposed dogs, corresponding dogs of such pairs being adapted to engagea car to prevent movement thereof down one such inclined track portion,and the other dogs projecting' higher and being pivoted to swing freelytoward such first-named dogs but locked against such movement in theopposite direction, whereby a car may pass over such pivotal dog but notback again, said cable being sufficiently elevated along such rst trackportion to render both dogs operative but being depressed along theother track portion so as to leave only said pivotal dogs operative. i

Signed by me this 20th day of February, 1909.
